NSG Precision Cells is the home of the world's only NIST 930e UV/VIS Calibration Standards that never need recalibration due to material aging. For years, NSG has specialized in providing quality cuvettes, cells and microfluidic chips to help researchers get their work done more efficiently, comfortably and safely. NSG offers unique, high-grade NIST 930e replacement calibration kits manufactured with the precision that its customers have come to rely upon. NSG's product line includes a wide range of accessories including UV/VIS calibration standards, a fully complete UV cuvette line for spectrophotometers and fluorometers, plastic disposable cuvettes, micro cells, cell washers, and much more. NSG's catalog offering represents the most popular types and sizes of cuvettes according to the requirements of our customers.

The revolution is on with NSG’s NIST 930e replacement kit. This kit is an ideal replacement for the NIST 930e VIS photometric accuracy kit, which contains a 10%T, 20%T and 30%T filter set. The operational wavelength of this set enables a user to calibrate for photometric accuracy in the range of 400-700nm and save thousands of dollars in filters and calibration fees. Just one of the HF filters can do the job of several of NSG's competitors’ filters. If this weren’t enough, unlike all of our competitors, NSG’s solid-state NIST 930e calibration standards are the only on the market that never need to be recalibrated.

The absorbance/transmittance values of this kit entirely complies with that of the SRM NIST 930e. Moreover, the tolerances of NSG’s NIST 930e kit are actually tighter than those of NIST’s boasting +/- 0.0022au. The performance of the calibration standards of this kit are unrivaled. This product has optical densities of 0.1au (10%), 0.2au (20%), and 0.3au (30%), a wavelength range of 400-700 nm (this kit can be used for any wavelength within this range), tolerances or +/-0.0022 au and the filters have an external dimension of 12.5 x 12.5 x 45 mm, enabling them to fit in any standard spectrophotometer.

Included in the NIST 930e replacement kit is the Instruction manual, Certificates of calibration with NIST traceability and photometric accuracy data tables which are available for qualified customers.

What are the benefits of using the NIST 930e kit? Firstly, they are highly accurate and consistent spectrophotometer calibration every time. They never have to be replaced and never have to be recalibrated if used properly. Its scratch-resistant coating protects optical surfaces and can also be used in any spectrophotometer (with standard 12.5 x 12.5 x 45mm holder). This kit surpasses NIST 930e requirements and tolerances and is NIST Compatible.
